What happened:

When my first phal didn't bloom this year, I got a bit suspicious and dug him out of the moss that he was in to find lots of root rot. I cut off as much as I could and replanted him in a clay pot into orchid bark. After a few weeks, the lowermost leaf turned yellow and dropped off and the rest of his leaves went wrinkled and limp, so I dug him up again (poor guy) to find some leftover moss that was choking the inner roots by the heart of the plant, much of which was rotted out. I thoroughly went through and dug out all the moss, and he seemed to be doing better.
I've been watering him every few days, as soon as the bark dries out (2-3) and he WAS doing better until my roommates moved him from the table he was on to the windowsill on the past two nights since they needed to use the table. We live by NY, so to put it in perspective, it gets to be about 20 degrees here at night, and the windowsills (especially where they squished him in the corner up against the glass) drop down to about 40.

I watered him this morning, (thoroughly drenched with room temp brita filtered water) and read that I should put a bag over the leaves to keep in moisture. I checked the roots and they are doing fine. :D

Is there anything else I can do to try to save him?
I appreciate any help you could provide!

Thanks,
Jenn

It is too soon to know what will happen. Just wait, you should know in a few weeks to a month. Make sure the plant is getting some fresh air or it will rot.

Good luck,
